Optional Installation These connections are optional. Your UPS will function properly without these connections. 1 USB and RS-232 Serial Communications Use the included USB cable (see 1A) or DB9 serial cable (see 1B) to connect the communication port on your computer to the communication port of your UPS. Install on your computer the Tripp Lite PowerAlert Software appropriate to your computer's 1A operating system. RS232 USB 2 EPO Port Connection This optional feature is only for those applications which require connection to a facility's Emergency Power Off (EPO) circuit. When the UPS is connected to this circuit, it enables emergency shutdown of the UPS's 1B inverter. Using the cable provided, connect the EPO port of your UPS (see 2A) to a user-supplied normally closed or normally open switch according to the circuit diagram (see 2B). The EPO port is not a phone line surge suppressor; do not connect a phone line to this port. 2A RS232 USB RS232 USB 4-5 2B 7 201205048 93-3149.indb 7 6/19/2012 11:33:36 AM
